This article will examine how to deal with sugar addiction.

We will start with a brief history of all things sugar, followed by a look into the dangers behind that sweet taste.

We’ll then examine the science behind sugar, how sugar cravings affect people’s lives, and the best methods to break free from a sugar addiction.

This article also features a brief interview with Karen Thomson; a self-confessed “recovering sugar addict” who is leading the charge to bring sugar addiction into the mainstream spotlight.

A Brief History of Sugar

Sugar: that sweet, white powder that’s part of our daily lives.

When we think about it, we have to consider how we use it in our society.

The foods that contain it are a treat for our children; we even use it as a reward system for good behavior.

Every childhood memory of a birthday or Christmas, if you’re anything like me, is filled with the stuff.

It’s in almost everything in the supermarket from supposedly “heart healthy” breakfast cereals to TV dinners.

What most people don’t know is this: it’s addictive… and in the amounts we’re consuming it, it’s very harmful.

As study after study piles up damning the health impacts of sugar, we should remember how it wasn’t always this way.

In fact, sugar marketing originally portrayed it as a health food.

“Published in the interest of better nutrition profit.”

As you can see in the advertisement, much of the original marketing around sugar positioned it as a health food; a wondrous supplier of energy to breeze through life.

Now, however, things are very different.

How Does Sugar Impact Our Health?

Warning noises about sugar began to emerge in the early 1970s, as John Yudkin, a pioneering British professor, tried to warn the world.

With the rest of the nutrition community zeroing in on fat, Yudkin publicly wondered why traditional foods like butter, eaten for centuries, were getting blamed for the increasing prevalence of heart disease.

He stood alone in his identification of sugar as the dietary devil behind the trend.



The professor was a thorn in the side of the sugar industry, and there was a widespread campaign to both discredit and ridicule his work.

Fast-forward four decades, though, and many things the professor warned about have come to pass.

The Dangers of Sugar

Sugar in the Shape of a Skull and Crossbones.

Sugar is linked to a huge range of health problems, and the scientific evidence has become far too strong to ignore.

Here is a brief summary of research from recent years:

Sugar and Heart Disease

  • As daily calories from sugar increase so does cardiovascular disease mortality (1).
  • Individuals who consume more than 10% of calories from sugar have a 30% higher risk of death from heart disease. People who consume more than 25% of calories from sugar have triple the risk (2).
  • “Even moderate consumption of sugar for a short duration may cause substantial harm” (3).
  • One sugar-sweetened beverage a day results in an average 16% higher risk of heart disease (4).
  • Diets high in sugar induce many abnormalities associated with CHD risk including; elevated glucose levels and insulin, leptin resistance, and fatty liver disease among others (5).

Sugar and Cancer

  • Raised glucose levels switch on a growth pathway allowing tumors to survive (6)
  • Foods which contribute to hyperinsulinemia, such as refined sugar and flour should be eliminated from a cancer-protective diet (7).
  • Dietary sugar intake increases the risks of breast cancer development in animal studies (8).
  • A prospective study found that those consuming the most sugar (particularly sugar-sweetened beverages) had a higher risk of developing pancreatic cancer (9).
  • Increased sugar intake activates several oncogenic pathways to induce cancer development (10).

There is a wide range of studies that also link sugar to numerous other chronic diseases including Alzheimer’s, diabetes, fatty liver disease, and more.

Is Sugar Addictive?

Whether or not sugar addiction is real is a contentious point; many people absolutely believe that it is real, yet others feel we shouldn’t class it as an addiction.

Personally, I believe that sugar (and other refined carbohydrates) are addictive in their nature.

Picture this scenario:

You are sat at home on a Friday evening about to watch a movie. Despite eating a little while ago and feeling quite full, a huge craving to eat spinach and a pork chop suddenly appears.

So, you quickly grab some money and sprint to the shop in a desperate attempt to beat closing time.

You arrive at the shop exhausted, pick up the pork chop, but when looking at the spinach you feel like just one won’t be enough… so you buy three packs of spinach as a treat. 

After getting home, you eat all three packs of spinach and the pork chop. Afterward, you feel a bit guilty and wonder why you ate three packs of spinach.

Does it sound realistic? Actually, I’d be quite worried if you answer “yes” to that.

Presuming the answer is no; how about if we change the word ‘spinach’ to chocolate and the word ‘pork chop’ to a donut?

Does that sound more realistic? I think so.

And so do the millions of people who experience strong sugar cravings, and the uncomfortable, continuous urge to eat more of it.

What Are the Signs of Sugar Addiction?

A Sign Saying "Stop! Addiction"

There is a fine line between being “a bit greedy” and having an unhealthy obsession, so some people who are addicted may not even realize.

Here are some common signs of an unhealthy relationship with sugar:

  • Eating when you don’t want to, and feeling guilty or disgusted with yourself afterward.
  • Making excuses to yourself: “I’ll just eat it for this week, and then I’ll stop starting from September.”
  • Feeling an urge to eat when you are already full.
  • Buying a large amount of food and finishing it in one sitting.
  • Continuing to eat despite being uncomfortably full.
  • Eating the food alone, because you don’t want family/friends to see how much you’re eating.
  • Hiding the food you eat from others, being careful to throw food packaging and receipts out before anyone sees.
  • Instead of eating the food slowly and enjoying the taste, you eat it rapidly until it’s all gone.
  • Eating emotionally – going out and buying food because something upsets you. Eating to make yourself feel better.

If you are experiencing more than a few of these symptoms then it’s likely you have some kind of sugar addiction.

The Science Behind Sugar Cravings

The Chemical Structure and Formula For Dopamine.

So, how might sugar “addiction” work?

When humans find something pleasurable, dopamine levels in our brain surge. This effect is often seen with addictive drugs such as opiates. The area of our brain where this takes place is known as the ‘reward center’.

Such drugs become addictive because we want to experience the ‘feel good’ factor again. As time passes, though, we sensitize and the dopamine effect becomes weaker and weaker, encouraging us to take more drugs to get the same effect.

What you may not know is that sugar stimulates this dopamine release in much the same way (11).

When you consume sugar, it hits your bloodstream almost instantaneously and spikes dopamine levels to give you a ‘feel good’ feeling.

This is a kind of evolutionary feature that tells us to remember something that we feel is good for us. It was particularly useful when we had to scavenge for food in the wild and avoid the many poisonous foods abundant in nature.

The sweet (and safe) taste of berries, for example, was something that should be reinforced at that time.

The problem is that we still have this feature in today’s world of hyper-processed food.

Surrounded by sugary food every time we leave the house, and desperate for our next dopamine hit, it’s not hard to understand why so many people have problems with sugar.

What Do Studies Say: Is Sugar Addiction Real?

Firstly, there are obvious ethical reasons why we can’t cage a group of humans and try to induce an addiction in them, so we have to mainly go on animal studies here.

There are a few that show sugar can be a powerful drug which encourages dependency:

  • In animal studies, rats fed a sugar solution over 21 days showed increased dopamine and less acetylcholine (a satiety response to food) release (12).
  • Sucrose-dependent subjects release more dopamine, have a delayed satiation response, and favor sucrose-containing food/drinks than non-sucrose-dependents. This is similar neurochemical behavior as seen in drug addicts (13).
  • A study comparing how sweet taste and also cocaine impact the reward center of our brain found that 94% of animals chose sweetened water over cocaine, even in those that were addicted to the drug. This study isn’t really relevant to humans, but it’s interesting (14).

Overcoming Sugar Addiction – 5 Ways to Beat It

A Picture Saying "Journey To Recovery" (Addiction Theme).

So, you feel like you’re addicted to sugar. How can you stop sugar cravings?

Unfortunately, there are no quick fixes and it will take time. However, I find that these five things help people a lot:

Stage One: Share Your Problems

The first priority should be to tell someone close to you about the trouble you are having.

Stop hiding it inside. Who you tell is up to you. It could be a friend, family member or even a teacher or co-worker.

A problem shared is a problem halved. By admitting you have a problem in this way, you have taken the most important step to fixing your sugar habit and recovering your health.

Instead of keeping your sugar addiction secret, you are being open about it and taking responsibility for positive change.

Stage Two: Clean Out the House

The best way not to be tempted by sugar? Make sure you have none of it in your house!

You can’t control all the environments you’re in, but this is the one you can control, making it the priority.

Make sure your house is stocked with lots of healthy food and that there are no sugary snacks calling out your name.

Stage Three: Optimize Your Diet

Cutting out added sugar alone isn’t enough. Food with high carbohydrate density such as rice, bread, pasta and juice

Foods with high carbohydrate density such as rice, bread, pasta and juice all have a very similar effect once inside the body. All these foods rapidly convert to glucose.

A great way to cut out your reliance on sugar would be to choose a low-carb meal plan full of healthy fats.

Eating a nutrient-dense diet will provide your body with the micronutrients and healthy compounds it needs.

As a result, it should help lower cravings for sugar.

Stage Four: Can’t Control Yourself? Be Prepared.

So you are eating a healthy diet now – but only at home.

Despite your best efforts, maybe you just can’t control yourself when you are surrounded by shops, bakeries, and cafes selling tempting treats.

So what can you do?

  • Take lots of healthy snacks (see point 3) to work; eat them if you start getting a craving.
  • Only take the money you need to work/school with you.
  • Leave your bank cards at home. If you don’t have money, you can’t spend it.

And if you do find yourself entering a fast food chain, then make a healthier choice.

Stage Five: Join a Supportive Online Community 

Maybe you just need someone to listen to you, or a group of people – strangers even – with whom to share your thoughts each day.

Humans are social creatures and discussing your problems with other human beings can really help.

Sugar cravings will ease with time, so just adopting these five points until you have better control can really help.

How to Deal with Sugar Addiction

A Sign Saying "Sugar Free" (Addiction Theme).

Now that we’ve examined the main issues around sugar addiction, it’s time to hear what a true expert has to say about it.

Karen Thomson is a former sugar addict but through the adoption of a low-carb diet full of healthy fat she has managed to beat her addiction and turn her life around for the better.

She is now using her passion and dedication for health and wellness to help people from all over the world who suffer from sugar addiction. And that’s what makes her a nutrition hero.

I had the chance to ask Karen a few questions about how we can recognize and deal with an addiction to sugar, and she kindly provided some information to help you all.

Here is what she had to say:

What would you say is the biggest difference between a simple food craving and a full-blown sugar addiction?

Karen: We all experience cravings. What differentiates a ‘normal’ food craving and an ‘addictive’ food craving is the lengths the person will go to in order to feed that craving. As with other addictions, sugar addicts will go to extreme lengths to get their ‘drug of choice’.

I know that my husband can lie in bed and say: “I wish I had a chocolate” and that’s where it will end. In the past I would lie in bed and think: “I wish I had chocolate”, then two minutes later: “I really need chocolate”, then two minutes later: “I have to have chocolate” and then a minute later I find myself in the car, in my pyjamas, and on my way to the shop in the dark of the night to buy chocolate.

This basic food craving has turned into a compulsion and despite the negative effects it has on my health and safety, I still put my intense desire to have it ahead of everything else.”

From your experience, what is the biggest obstacle people have in regard to quitting sugar?

Karen: Believing that everything in moderation is key: I cannot tell you how often I have heard this as an excuse for people wanting to ‘have their cake and eat it’. The problem with a true sugar addict is that one slice of cake is never enough and instead of eating cake we eat feelings of guilt, shame, and fear along with it.

This could in turn set off a vicious cycle of binging, feeling guilt, shame and fear, and then needing to eat some more cake to push those uncomfortable feelings away.

So.. if someone is having these kinds of feelings, what can they do? What would be your best advice to someone dealing with a sugar addiction?

Karen: Find a supportive community. You are NOT alone.

Thanks. It is very great and informational article


A really good article. For me another big help was understanding how the circadian body clock works and consequently trying really hard to not eat after 7pm. By avoiding those unnecessary carb and sugar evening snacks I avoided the strong cravings and consequently started sleeping much better than I ever have.

Thanks. Great article!


Is there any scientific study randomized or similar confirming the information or is just supposition, no direct cause-and-effect Association?
